I'm trying to determine a better word to describe a role for an entity that checks for uniqueness between two objects.
For example: if I wanted to check for duplicate records in an excel spreadsheet, is there a single non-compound word to describe the tool which executes that action.
Right now we are going with "DuplicateChecker", but it feels a bit ... unrefined.
DuplicateChecker
so asked for a better name. This is a programming question.
